Have recently moved and had a rewire including central heating Block Terminal tidy up. This by a qualified electrician.
The boiler is a Potterton PrimaF with one Zone Valve.
Unfortunately the Central Heating will only fire up with the Zone Valve manually locked. It wont operate electrically.
I'm sure the BT is incorrectly wired. He did renew the valve.
The boiler has two3 core cables going into it with a 3core coming out to the pump.
Electrician on holiday for three weeks!
Any help/advice appreciated especially wiring diagram for the Potterton circuit board and general wiring for this type of system.
Best wishes from,
Gibson.
